Serial No. 733,477 1 In. Great Britain July 31,1933 4 cl ims (01;late-44 v r 7 p passages or spaces M which extend beneath these Thisinvention relates to cooking and like stoves-heated by oil or gas andhas for its object througha chimney or exit flue. v The presentinvention consists in a cooking or like stove wherein a combustionchamber is propanying drawings which illustrate by way of example aconstruction according to the invennon and in which:--- r v Fig. 1 is aplan view of a stove constructed according to this invention,

Fig. 2 is a longitudinal vertical on the line A-A of Fig. 1,

Fig. 3 is a vertical cross section line BB of Fig. 1 and Fig. 4 is afurther vertical cross section taken on the line CC of Fig. 1.

In the construction illustrated, a stove is shown which comprises asubstantially rectangular casing I having combustion or burner chambers2 and 2a formed at its ends. Between the burner chambers are disposedtwo rows of ovens or cooking chambers 3, 3a and. 3b and 4, 4a. and 4b,and vertical and horizontal passages 6, 1 and I4 and 6a, 1a and Ma whichenable the gases of combustion to pass around the ovens. The gases fromthe burner chambers 2 and 2a make their exit through outlets 8 and 8arespectively at the top of the inner sides of these chambers, and

section taken taken on the the said partition ID. The gases ofcombustion leaving the combustion chamber 2 pass through the outlets 8into the passages 1 above the ovens 3a and 4a, the gases being preventedfrom passing to the remaining ovens owing to the interposition ofpartitions l3 in the vertical passages 6 immediately beyond the ovens 3aand 4a. These partitions extend downwardly through end of the verticalpassage 6 nearestthe said chamber is closed by-a baflle 25. I

r. The 1 combustion "chamber 2a communicates with the vertical andhorizontal passages 6a,

la and Md around the' ovens 3; 3b, i and 4b,

through the outlets 8a, the passages around the capable of separationfrom those chimney 9 through similar to the lines l6. This chimney isdivided as shown in Figure 1 into four parts by partitions l8 crossingeach other at right angles, each part of the chimney communicating witha separate exhaust passage, that is to say, two sections of the dampersll, through the outlets I511 and separated lines I 6a. Each section ofthe chimney is provided with a separate control damper the position ofwhich is shown by indicators E9 on the exterior of the chimney and whichenable the draught around the various ovens to be regulated.

The dampers [1 are also provided with external operating handles 20 andthe operation of either of these dampers closes one of the passages 1ain such a sages 6a between'the sides of the 3b and 4 and 4brespectively.

The top of the stove and of the combustion chambers consists of a numberof removable plates 2| to facilitate cleansing whilst the ovens areprovided with doors 22 hinged at their lower ends at 23 and adapted toopen against resilient checking devices 24 which operate to preventbreakage due to sudden opening of the oven doors.

chambers 2 and 2a produce flames impinging one on each side of therespective partition ill, a very intense heat being thereby concentratedon the partition to assist in effecting complete combustion of the fuel.When, however, the intense heat produced by the two burners in thecombustion chamber 2 is not required and one burner only is employed, aportion of the gases from one end or part of this combustion chamberwill pass through the partition Ill and will ultimately be distributedthrough the outlets 8 to the passages surrounding the ovens 3a and 4a.Similarly when one burner only is operative in the combustion chamber2a, the hot combustion gases will circulate around the ovens 3, 3b, 4and 4b, or if the dampers H are closed around the ovens 3 and 4 only. Itis to be understood that additional dampers may also be employed so thatonly one of said ovens is heated or to enable the ovens 3 and 31) or 4and 4b to be used as a unit.

I claim:-

1. A stove of the class described having a combustion space, a vertical,refractory perforated ignition wall dividing said space into a pluralityof chambers, spaced apart ovens, separate passages for conducting heatedgases for heating said ovens, said passages communicating with saidchambers on opposite sides of said ignition wall, and a fluid fuelburner positioned in each chamber to direct flame against said ignitionwall whereby one burner may be used to heat all ovens or all burners maybe used.

2. A heating device of the class described having a combustion space, aperforated ignition wall dividing said space into a plurality ofchambers, separate passages each on a different side of said ignitionwall for conducting heated gases from the separate chambers, and a fuelburner positioned in each chamber to direct flame toward said ignitionwall whereby one burner may be used to heat both passages or all burnersmay be used.

3. A stove of the class described having a combustion space, a vertical,perforated refractory ignition wall dividing said space into a pluralityof chambers, ovens at one side of said space in spaced relation, meansproviding separate heating flues for said ovens having portions locatedin the space and separately communicating with said chambers on oppositesides of the ignition wall, and a fluid fuel burner positionedin eachchamber to direct flame against said ignition wall whereby one burnermay be used to heat all ovens or all burners may be used.

4. A stove of the class described having oven means in spaced apartrelation, a refractory partition in the space between said oven meansproviding heating fiues for conducting heated gases for heating saidovens, a combustion space beyond one end of said oven means having aperforated ignition wall substantially in line with said partitiondividing the second mentioned space into two chambers communicating onopposite sides of the partition with separate passages, and a fluid fuelburner positioned in each chamber to direct flame against said ignitionwall whereby one burner may be used to heat all ovens or all burners maybe used.
